What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveNuclear actin is involved in transcription regulation by recruitment of histone modifiers and chromatin remodelers to the regulatory regions of active genes. In recent years, further attention has been focused on the role of actin as a nuclear protein in transcriptional processes. In the current study, the epigenetic role of nuclear actin on transcription regulation of two stemness (OCT4 and NANOG) and two differentiation) NESTIN and PAX6) marker genes was evaluated in a human embryonal carcinoma cell line (NT2) before and after differentiation induction. MATERIALS AND
methodsIn this experimental study, differentiation of embryonal cells was induced by retinoic acid (RA), and quantitative real-time polymerase chain reaction (PCR) was used to evaluate differential expression of marker genes before and 3 days after RA- induced differentiation. Chromatin immunoprecipitation (ChIP) coupled with real-time PCR was then undertaken to monitor the incorporation of β-actin, as a functional component of RNA polymerase II, in the regulatory regions of marker genes.
resultsData showed significant change in nuclear actin incorporation into the promoter regions of NESTIN and PAX6 after RA-induction.
conclusionWe emphasize the dynamic functional role of nuclear actin in differentiation of embryonal cells and its role as a subunit of RNA polymerase II.
